LSA noise
specialists provide public and private sector clients with comprehensive
acoustical assessment services to comply with the California Environmental
Quality Act (CEQA), the National Environmental Policy Act (NEPA), and
local requirements. LSA's services range from construction-level analyses
of transportation and development projects to the assessment of planning
documents and studies of unique sources of noise, such as airplanes,
trains, and industrial equipment.
To determine the potential noise impacts of each project, LSA uses state-of-the-art
computer models and assessment protocols developed by the U.S. Environmental
Protection Agency, the Federal Highway Administration, Caltrans, the Federal
Aviation Administration, and city or county governments with jurisdiction
over LSA's project sites. Computer models used include TNM and SOUND32
for motor vehicle noise related to roadway and freeway projects and INM
for
the impacts of aircraft noise.
LSA presents study results in concise, nontechnical language that is easy
for decision makers and laypeople to understand. Our board certified staff
is available for presentations and deposition or testimony as expert witnesses
in public hearings and courtrooms.
SERVICES INCLUDE THE FOLLOWING:
- Instrument assisted noise and vibration field surveys
- Noise impact analysis for commercial and industrial stationary sources
- Airport and rail noise impact analysis
- Federal Aviation Administration Part 150 noise/land use compatibility studies or airport expansion
- Design of transportation-related sound walls
- Evaluating the performance of sound insulation

California Speedway
Penske Motorsports
Fontana, California
LSA conducted air quality and noise impact evaluations for the one-quarter mile drag strip within the California Speedway facility in the City of Fontana, California. Noise monitoring was done during a test race at the site and in adjacent residential areas. Noise levels measured were used to evaluate potential noise impacts associated with the street-legal drag race. Some mitigation measures were identified to reduce the noise impacts to less than significant.... more
